Installations for obtaining water from air without electricity

At the initial stage of construction, many have no water supply. Not everyone drills a well or runs a water supply right away. Although, in the US, most private sector construction projects begin with the laying of communications.

I remember the times when I brought water for my needs from a neighboring lake in 80 l barrels. In theory and even in practice, there are installations that allow you to obtain water from atmospheric moisture. Let's look at some designs that do not require mains power or do not require any electricity at all.

Installing AirDrop. It consists of an above-ground part, a bar with a solar battery for an air circulation fan and an underground part with a copper coil in which moisture condenses.

In summer, the air can have a humidity of up to 80%, even in our climate. Passing through a coil cooled by soil, water condenses on its walls and flows into the reservoir. The water is pumped out by a battery powered pump. They are recharged by the same solar panel.

Another installation that does not even require electricity from the sun is the Waterseer. Here, the fan drives air in the presence of wind. I have not found pilot or industrial installations of this option. Only a description of the invention. Perhaps it has remained at this level.

But experts from the Italian architectural bureau Architecture and Vision (Arturo vittori and Andreas Vogler) made not only the project, but also installed experimental structures in Africa, in places with problems with drinking water:

The system does not require electricity. Uses only natural processes of ascending air currents. Experts have experimented for several years and achieved maximum performance. To do this, they had to mount a "skirt" around the tower. The tower is made of reed, and inside there is a facade mesh and film.

It works like this: the space around the tower is covered with a canopy (skirt) and has a slightly low temperature. Inside the tower, it heats up and rises upward, drawing colder air. Moisture condenses on the mesh and flows into the container. Works mainly in the morning hours, in fog or at night. Collects dew. It also collects rainwater. Experience has shown that such a tower can collect up to 90 liters of water per day in a humid African climate.

The effect of condensation of dew on a web in the morning hours, or during fogs is used.

Mobile unit for condensing water from air. In the morning, 0.5-1 liters can be collected. But you can't drink such water. It is distilled. In order for it to become drinkable, a number of salts must be dissolved in it in small concentrations. I read that such sets are on sale.

Other "kulibins" offer the following schemes for condensation of atmospheric moisture:

You need to add dishwashing nets to the pipe - the efficiency will increase. And the fan is powered from a solar battery with a battery. A decent amount of water in tens of liters can be collected in a week.

Another option: a sealed container filled with pebbles or rock is buried to a depth of 1-1.5 m or deeper in a shaded place. At the bottom of the tank there is a container for collecting water. Air is blown through the volume from the surface. Moisture condenses on cold stones and flows into a container, from which it is pumped out. The fan and pump are also powered by a solar battery.

Of course, it is easier to bring 20-40 liters of water with you than to manufacture, perhaps, installations that are ineffective in our climate. The article is only as information about the fundamental possibility of obtaining water from the air.
